New Delhi:

Aam Aadmi Party chief Arvind Kejriwal hit out at the Congress as the party took a formal decision today to not ally with his party in Delhi today. The Congress was "helping the BJP", he tweeted minutes after Sheila Dikshit said it was an "unanimous decision" by the state Congress, which has been accepted by party chief Rahul Gandhi.

Mr Kejriwal had earlier said the Congress was unwilling to ally with his party in Delhi and he was "fed up" with reaching out to the party.

After the rebuff today, he tweeted:

At a time when the whole country wants to defeat Modi- Shah duo, Cong is helping BJP by splitting anti-BJP vote. Rumours r that Cong has some secret understanding wid BJP. Delhi is ready to fight against Cong-BJP alliance. People will defeat this unholy alliance. https://t.co/JUsYMjxCxy
